2.2 Safety Considerations
If failure or malfunctioning occurs during operation of the
717 Sample Changer, the Metrohm Service Department should be
consulted.
If opening the instrument is unavoidable, the following safety pre-
cautions are to be strictly adhered to:
Before opening the instrument disconnect it from all electri-
cal sources. Make sure that all main cables have been dis-
connected.
Only in exceptional cases should the instrument be opened while it
is switched on. Because parts that conduct current are exposed in
this case, this should only be undertaken by an expert who is ac-
quainted with the associated dangers.
Electronic components are sensitive to static electricity and can be
destroyed by discharge. Before touching any components inside
the instrument, both the person and his tools should be grounded
by grasping a grounded object (for example: a metallic part of the
casing of the instrument or a radiator) in order to eliminate any
static electricity.
When peripheral instruments are connected to the 717 Sample
Changer, the sample changer and the instruments to be con-
nected have to be switched off, otherwise all instruments could
suffer damage.
If it becomes apparent that the instrument can no longer be oper-
ated safely, it must be put out of operation.
